Hire Kubernetes Engineers

The honest answer depends on the half-life of your kubernetes engineer surface area. If you expect to keep investing in Kubernetes and Helm work over the next 18-24 months, a specialist kubernetes engineer will out-deliver a generalist on day-30 throughput and stakeholder confidence.

If your team is under ten people, or kubernetes engineer responsibilities are spread across two or three roles already, hire a strong generalist who has shipped this work in anger at least twice. The cross-disciplinary pattern recognition will pay for itself the first time priorities collide.

On Haystack we surface both - filtered by whether the candidate self-identifies as a kubernetes engineer specialist and verified against their last two roles. Expect to pay around £80k–£105k for a mid-level UK hire, scaling toward £110k–£155k for senior.

A great kubernetes engineer is not the one with the longest CV - it is the one who has owned a hard Kubernetes call and changed how they work because of how it landed. Across the devops hires we have placed in 2025-2026, the same patterns keep showing up.

Every discipline has its own pattern of plausible-sounding answers that fall apart in production. For kubernetes engineers, these are the patterns that most often correlate with a six-month regret hire on the employer side.

When teams ask us how to evaluate a kubernetes engineer beyond a CV and a chat, we recommend a 90-minute paid take-home that mirrors real work, not a trivia quiz. The brief below is one we have refined with employers hiring across devops teams.

Give the candidate a small, intentionally imperfect artefact tied to "operate production kubernetes clusters". Their task is to add a second capability - tied to "own networking, service mesh and policy" - while keeping existing behaviour intact. Then grade in three parts.

By week one, the new kubernetes engineer should have shipped a small, low-risk artefact to production or a stakeholder - a docs fix, a small process change, a first review on someone else's work. The goal is to validate the loop, not to ship anything heroic.

By week two, the kubernetes engineer is shadowing the active workstreams, attending standups in observe-mode, and asking pointed questions about why specific decisions were made. If they are not asking those questions, the hire is going to plateau.

By day 30, they own one cleanly-scoped slice of the kubernetes engineer surface area, have published a public ramp-up doc, and are the named point of contact for stakeholders inside that slice. Every Haystack employer gets a structured onboarding template, so you are not reinventing the playbook each hire.
